Help identify an old set of octopus regulators

[DaleC]

If I were at a garage sale I would not pay more than $20 and I have gotten similar for less. Hope it's a cheap drysuit

As I stated in first post-

JUNK

$15.00 to $25.00 US dollars..

It is a common regulator set up and no longer in demand and has no "Romance" associated with the unit.

good luck,

oOBigDaveOo,

"...fairly difficult to service and use..."??? No, they aren't. The Calypso is a fairly simple regulator, with a flow-through piston design and adjustable interstage pressure. The second stage is also simple to service, and has a very good venturi built into it. This regulator tested very well with the U.S. Navy, and these test results are in the Rubicon Research Repository, and can be downloaded from that site (see the link). The Calypso VI (which is your regulator) can be seen on page 54, and the test results can be seen on page 266-271.

Did the conshelf series regulators follow the calypso. I've been shallow diving with my conshelf XI and asking myself if I really need to go back
to my 500 dollar regulator for the shallow stuff. There are days it seems it breathes as nice as my g250v balanced but then days when it seems
a bit more effort. It's probably just me. I use it with what I believe is a conshelf 14 or 21 first stage and it breathes pretty nice for an old reg and
definitely durable. The XI second stage looks almost identical to the calypso shown.
